Gerald Aardsma explains, "Radiocarbon is not used to date the age of rocks or to determine the age of the earth.

However, even chemically identical atoms can have different masses – these ...It was developed right after World War II by Willard F.Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.Radiocarbon dating is a method of estimating the age of organic material.— Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. — A new material with micropores might be a way to fight climate change.

Buckyball sandwiches combine fullerenes and graphene. Scientists have created crystals that capture carbon dioxide much more efficiently than previously known materials, even in the ...

— Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled.

But soon these discarded discs could take on a different role: ...

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.

The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry.

Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
